Visual Inspection

Visual Testing (VT)

Visual Testing (VT) is the most fundamental form of non-destructive inspection and involves the direct visual examination of a component to identify surface defects, damage, or irregularities. Inspections are carried out using the naked eye and the expertise of a qualified and competent inspector.

VT can be used for both internal and external surface inspections across a wide range of components, including:

• Forgings

• Castings

• Pressure vessels

• Pipework

• Weldments

Visual inspection is commonly used in conjunction with other NDT methods, such as Magnetic Particle Inspection (MPI) or Dye Penetrant Inspection (DPI), which provide more detailed detection of surface-breaking defects.

While VT is less technologically advanced than other NDT techniques, this simplicity offers key advantages:

• Minimal equipment requirements

• Cost-effective inspection method

• Rapid deployment on site

• High reliability when performed by a skilled inspector

A well-trained VT inspector can identify many early signs of deterioration, poor workmanship, or service-related damage, making VT an essential first step in any inspection regime.
